Mechanism for reporting with channel status waving

Abstract

Embodiments of the present disclosure propose a solution for reporting with channel status waving. According to embodiments of this present disclosure, a terminal device determines one or more time durations for reporting and preconfiguring with the channel status waving. The terminal device transmits parameters related to channel status and/or adjusts its power in accordance with the one or more time durations. In this way, it can improve the reporting of channel status information and configuration efficiency with reduced overhead.
